Global biomethane supply increased by an estimated 16% (1bcm) in 2022 to close to a record 7bcm, according to new IEA data.
The increase was primarily driven by the EU and the US, which together account for approximately 90% of incremental biomethane supply. EU biomethane production rose by an estimated 15% (0.5 bcm) to close at 4bcm, spurred by 65% growth in France (442 plants).
The US remains by far the largest biomethane-producing country in the world, a position it has held since 2019. The country’s biomethane output grew by an impressive 20% (close to 0.4 bcm) to reach 2bcm in 2022, accounting for almost 30% of global biomethane output. It currently has over 250 operational biomethane facilities, with around 220 additional plants under construction or planned.
Municipal solid waste remains the single largest source of feedstock, underpinning approximately 70% of total US biomethane production. Agricultural waste accounts for
almost 20% of biomethane feedstock supply, while food waste and waste water account for the remaining 10%. Supply growth in 2022 was largely driven by biomethane facilities relying on agricultural waste as a feedstock.
